The main objective of this article is to describe a problem portrayed into critical human conditions in urban margins characterised by the deprivation of most basic human needs, housing in particular. This is undertaken in search of alternative ways that promote a bigger plan of urban regeneration while exploring whether faith-based action makes a special contribution to this goal, both sustainably and innovatively. The article uses a case study of faith-based action from the City of Tshwane in Gauteng province, South Africa. It first begins with constructing an untoward paradoxical narrative of urban marginalisation and housing crisis scenario. It proceeds, responding to marginalisation in light of values of spatial justice and housing. This insight leads the article to sketch a paradigmatic point of departure addressing urban margins, looking at the sustainable livelihoods framework and its basic tenets that mobilise livelihood assets (tangible and intangible) to tackle urban marginalisation from its roots. The article moves on to explore a contribution of faith-based action in urban regeneration through housing value. The penultimate point of the article engages the case study followed by drawing the general conclusion and way forward. The article adds to the existing literature, employing an epistemological approach that integrates multidisciplinary sources and empirical reports on urban marginalisation. Unstructured interviews, participatory observations and personal experience on housing practice help to achieve the main objective of the study.
